Mmh, my nick was actually born when I started cracking....
I used to be the "old man" in various groups and I like The Simpsons.
Allthough I "retired" from cracking, I still love this name, cos Simpsons' Monty Burns is a real rotter, and so am I, at least, that is what my wife keeps telling me
Not much more to say, only that I use some other nicks on various occasions....
